Cut the mango into two halves along the stone. Score each half into squares without cutting through the skin. Turn out the halves with your thumb and slice off the cubes. Or use a mango slicer.
Slice the chicken fillet into 1.5 cm cubes. Season with salt and pepper. Heat the olive oil in a pan and fry the chicken for about 5 minutes until it is cooked.
Finely chop the onion. Heat the wraps according to the instructions on the package.
Spread the wraps with mayonnaise. Divide the salad leaves over the wraps. Add the mango, chicken and red onion. Season to taste with salt and pepper. Roll up the wraps as tightly as possible and slice them at an angle to serve.
